A children’s classic that has been part of Japanese bookshelves for more than five decades is preparing for television. It’s Little Mouse’s Red Vest, also known as Nezumi-kun’s Vest (or Nezumi-kun no Chokki). Japanese broadcaster NHK will be bringing the TV anime adaptation.
Yoshio Nakae and Noriko Ueno’s Little Mouse’s Red Vest will begin airing on April 4th, 2026, at 9:30 JST. The series will be broadcast on NHK Educational TV every Saturday at 9:30 am starting April 4th. There’s no information on any global (English) release yet.
The original work, often referred to as the Mouse’s Picture Book series, first appeared in 1974. A collaboration between author Yoshi Nakae and artist Noriko Ueno, it was published by POPLAR Publishing. The books celebrated their 50th anniversary in 2024.
The collection has reached 43 volumes, with the recently released Mouse Who Wants to Be an Artist marking the 43rd entry. Since its debut with Nezumi-kun no Chokki in 1974, the series has accumulated more than 5 million copies in circulation in Japan and over 16 million internationally.
Noriko Ueno, who illustrated the series, died in February 2019. Her softly rendered artwork remains central to the identity of the books. The anime adaptation aims to translate that visual style into motion while retaining the qualities that have defined the series till now.
